I updated my machine yesterday to Ubuntu 17.10 and suddenly I can no longer use the launcher to start Atom editor. It was installed as a snap and can be launched via the software app (it is installed) but it will not show up when doing a search . I cannot set it as a favorite either.
The version of my Atom snap is 1.21.1 (updated 10/19/2017).
$ snap --version
snap 2.28.5+17.10
snapd 2.28.5+17.10
series 16
ubuntu 17.10
kernel 4.13.0-16-generic
There's a thread about this but I can't find/understand a solution there.
Update: I made a bug report on the developer's github. Atom says that they don't maintain the snaps, so it is not their issue.
